I thought it was nose down for the second phase of compass calibration (as per manual and previous DJI quads).
I really think the app was too lazy to get a proper (side) drawing of the spark.
I guess not many have complained about this or maybe we are so lucky that sideways compass dance works just as well as nose down.

I have done it as in the app and rechecked the calibration from a .DAT file record using CsvView. That's just fine. I think they just calibrate the Z component in the second step and the position don't mater as it is rotation over the Z axis.

That's great stuff man! Thanks for sharing. It's interesting why it would stress the nose down orientation, but in the end not really matter. Maybe they use a default App template for all the drones and that was overlooked? Or the technology passed the need for that step and they neglected to remove it. Either way, I hope DJI's Quality Control starts to pick back up soon.

Thanks for the informative video! However, I find my compass calibration almost always fails. Maybe 8 out of 10 trials will fail. Nowadays I just depend on the auto detection and do not calibrate when there's no prompt.

It is all matter where would come disturbance. Often the one you cannot see are under ground.
So increasing the distance will be good, but the best would be to go a more suitable place for calibration.

Yes but don't calibrate at the place you get the message without understanding why you get the message. Often you move a little or take-off from hand and you are good.
The message says "Calibrate" but it should be understood as "Compass report wrong data, don't take off, without checking".

Because on the ground you can have steel bars, concrete filled with i dont know what. This will affect the magnetic field and thus the compass.
And do not calibrate it with you turning with it, it needs to be on its axis. Why, cause it might have been you that cause the interference (or devices on your body).
